In reply to MGC:
First time I tried that happened too. Cutting down the amount I used stopped that problem.
On the washing machine side, it seems using top loader detergent in a front loader seems to result in too many bubbles.
I'd be happy to use washing up detergent in a top loader.
On a related note, not knowing what detergent would do to the dwr on pertex endurance I just washed my jacket without detergent and it came out very clean.
